I've looked at the sources, and I think I know what the problem is - this audigy model is not controlled by an ac97 and neither the OSS4 or FreeBSD drivers are aware of it... Changing this will require some recompilation of either of them, and I'm not sure I can be successful (I'm not a dev). If you are prepared for this, let me know.

You've done a great job so far and I do understand that you are not a dev (either way, whatever comes about from this, you're on my christmas list now! No joke. If we have to get into altering the kernel then I will have to think about that for a while and decide if that fits with the "making this possible with a default PC-BSD install". However, having said that, getting this sucker to work at all with PC-BSD is the primary goal. As long as I have time to make sure I've a vanilla kernel and some files backed up... I'll be ready to move forward. Meanwhile, the ossmix output is kind of interesting...

Ok, actually having a little bit of trouble here as there is no /usr/lib/oss directory and a search shows that there is also no oss_sblive.conf anywhere in the system. There is, however, a /usr/local/lib/oss/conf/oss_sblive.conf.sample but that is not a big help at the moment. I sense that this may have something to do with how PC-BSD differs from FreeBSD. Then again... what are your thoughts?

If/when this doesn't work, we can try modifying the native driver (a bit easier than modifying oss_sblive). Unfortunately, this may involve rebuilding the kernel.... Anyhow, looking at the native driver source (this file), I find the following:

at about line 527 and hope it will work. I am unable to help much further with this, as driver programming is not my forte... Perhaps the freebsd-multimedia list can help more (with the native driver) or the oss4 dev list (with oss4).

I think line 527 may be left blank for a reason. It is possible that Yuriy attempted adding support for the card but the docking station interplay would not function... so he removed it and just left the line blank. It's also possible that he did not have the docking station physically available to him (in my experience with Russia, it is likely that this system is not readily available for purchase). Without any analog outputs on the card (see pic: http://www.emu.com/products/zoom/15189.html ) I'm pretty sure that a full test would have been difficult. Also, the converters in the 1616m are a bit different than the 1212m (not sure how this relates however). They have to be switched somehow internally, within the dock itself not the card... you can actually hear switches being flipped, when you change between the low 44.1k-88.2k and the high 96k-192k sample rates.

None the less. Thank you very much for all of the help this far cesium. I don't think we've wasted any time. This card/docking-station system is still out there, current and viable so it does need documented even if it's just some poking around in dark corners. Till next time. o/
